1. In a given year, residents of a country spent approximately $58.2 billion on their pets. Of this amount, $15.6 billion was for veterinarian bills. What percent of the total was spent on veterinary care?
2. Diners frequently add a 15% tip when charging a meal to a credit card. What is the total amount charged if the cost of the meal, without tip, is $21?
well, surely that would be
15.6/58.2 * 100% = ____%
21 + 0.15*21 = 21*1.15 = $_____
To find the percent of the total spent on veterinary care in question 1, you need to divide the amount spent on veterinary care ($15.6 billion) by the total amount spent on pets ($58.2 billion) and then multiply by 100.
Percent spent on veterinary care = (Amount spent on veterinary care / Total amount spent on pets) * 100
So, in this case, the calculation is:
Percent spent on veterinary care = ($15.6 billion / $58.2 billion) * 100
To solve this, divide $15.6 billion by $58.2 billion and then multiply the result by 100.
Percent spent on veterinary care ≈ (15.6 / 58.2) * 100 ≈ 26.83%
Therefore, approximately 26.83% of the total amount was spent on veterinary care.
For question 2, to calculate the total amount charged when a 15% tip is added to a meal costing $21, you need to add the cost of the meal to the 15% tip.
Total amount charged = Cost of the meal + (Tip percentage * Cost of the meal)
Since the tip percentage is 15%, the calculation becomes:
Total amount charged = $21 + (0.15 * $21)
To solve this, multiply $21 by 0.15 and then add the result to $21.
Total amount charged = $21 + (0.15 * $21) = $21 + $3.15 = $24.15
Therefore, the total amount charged when a 15% tip is added to a meal costing $21 is $24.15.
